Static equilibrium thrust bearings

Hi all, I have a question regarding thrust bearings. For my statics class we've been tasked with finding equilibrium forces for a modular band saw. The thing I'm having trouble with is the many bearings in the part. My only question is that if the only known given force is tension in a pulley going straight down in the -y axis, how does it affect the thrust of bearings? All the bearings are axial to the x axis. Am i just to assume that all the thrust forces are zero since there are no external forces acting in the x direction?
